This speak: Another in-depth discussion of the book cover, more talk about how big of a D-bag David is, more character development for Cassie, poor cousin Saddler, Visser Tony’s hologram-ception plot, another mission gone awry, the many deaths of Tobias, and one of our favorite morph-on-morph showdowns in the entire series! All that and more in our review of Animorphs #21, The Threat.
